Spicer Front Axle Outer Vacuum Seals & Greasable U-Joint Overhaul Kit for Ford F-250 & F-350 (Dana 60, 1998-2004, Both Sides)

Completely refresh both front steering knuckles, stop gear oil leaks, and restore your automatic 4WD performance with this genuine Spicer Front Axle Outer Vacuum Seals and Greasable U-Joint Overhaul Kit. Specially compiled for leaf-sprung 1998–2004 Ford F-250 and F-350 Super Duty trucks (as well as 2000–2005 Ford Excursion models) equipped with a monobeam Dana 60 front axle, this premium dual-side service package features everything required to fully overhaul your front wheel ends simultaneously.

The outer wheel ends on early Super Duty platforms are notorious for vacuum leaks. The factory Pulse Vacuum Hub (PVH) system relies entirely on a sequence of tight rubber seals to engage the automatic locking hubs from the dashboard. Over time, road salt, mud, and continuous thermal cycling dry out the massive main outer knuckle seals, leading to automatic 4WD failure and allowing trail debris to contaminate the axle tubes. Additionally, dry front axle u-joints will cause steering wheel feedback, popping sounds during tight turns, and severe drivetrain vibrations.

This all-in-one overhaul bundle eliminates the guesswork of sourcing loose components by matching premium Spicer greasable universal joints with a complete, heavy-duty replacement seal sequence. Upgrading to the greasable u-joint design features an integrated zerk fitting, allowing you to easily flush away trail dust, mud, and road salt during routine oil changes to maximize drivetrain longevity.

Kit Highlights:

• Complete Dual-Side Overhaul: Packages 2 premium greasable front universal joints, 2 massive main outer knuckle vacuum seals, 2 inner axle tube oil seals, and the supporting hub assembly o-rings.

• Greasable Drivetrain Upgrade: Features rugged universal joints equipped with integrated lubrication fittings, facilitating fast preventative maintenance to protect your needle bearings against water intrusion.

• Genuine Spicer OEM Quality: Every seal and joint is manufactured to strict original equipment structural and dimensional tolerances, guaranteeing a reliable mechanical press-fit and a lasting pneumatic seal.

• Restores Factory Automatic 4WD: Replaces the critical, multi-lip outer hub vacuum seals to re-establish the strict air pressure retention required for error-free automatic front hub locking.
